To all whom z' may concern:

Be it known that I, I-IoLDMAN ROBERTSON, a citizen of the United States, residing at Farmington, in the county of St. Francois, State of Missouri, have invented certain new and useful Improvements in Car-Replacers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railway appliances and particularly to car replacers.

One object of the present invention is to provide a novel and improved device of this character which can be easily and quickly secured to the ordinary replacing frog so that the frog can be readily attached to the rail to hold the frog in place for operation.

Another object is to provide a novel and improved device of this character which is durable and strong in its construction and which is capable of attachment at any point along the railway. Y

Other objects .and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: l

Figure 1 is a top plan view of the invention shown in connection with a portion of a railway.

Fig. 2 is a side elevation viewed from the side of the railway.

Fig. 3 is a bottom plan view of the* shown in Fig. 1. e

Fig. 4 is a vertical transverse sectional view taken on the line 4 4 of Fig. 1, showing the connections between the parts of the device and the manner in which the device is clamped to the rail.

Referring particularly to the accompanying drawing, 10 represents a rail of a railway which is secured to the ties 11. Disposed longitudinally with respect to and inwardly of one of the rails and outwardly of the other` rail are the replacing blocks 12. These `blocks each are of the ordinary type now in use and have the upper portion inf clined downwardly and toward the rails, so that the wheels of the car or engine, when disposed thereon, will readily roll onto the rails. Secured to the inner face of each of the blocks, by means of the bolts and nuts 12, is a member 13, the lower end of which is reduced and threaded, as shown at 14, and is received through an opening 15 in the adjacent end of a horizontal member 16, which extends transversely under the rail. A nut 17 is engaged on the said reduced threaded portion 14 to hold the block and member 16 together in proper position. The outer end of the member 16 is reduced and threaded at 18, and passes through an elongated angle member 19 which engages on the base flange of the rail and at the outer side thereof. A nut 20 is engaged on this end of the member 16 to draw the angle member into firm engagement with the base of the rail, and the block into close proximity with the inner side of the rail, but at a sufficient distance therefrom to permit the flange of the car wheel to pass between them. It will be noted that the ends of the block rest on two adjacent'ties, while the member 16 extends transversely beneath the rail, between the ties. Thus the block can slide toward and away from the rail, when applying or removing the device.

The invention resides particularly in the means for securing the ordinary replacing frog on the railway ties and in proper relation to the rail, so that the frog can be more easily and quickly placed in position for use than the ordinary frog. Usually it requires the operator to crawl under a car or engine, close to the wheels, to spike the frog to the ties. Sometimes the tie is in such relation to the wheels of the car that it is practically impossible t0 drive the spikes. The present invention contemplates the application of a clamping means which is .readilyl attached to the ordinary frog by simply boring two holes in the frog and securing the clamp by bolts engaged through said holes. Thus the frog can be easily and quickly attached in position no matter how close the wheels of the the ties.

What is claimed is: The combination with a replacing frog having a vertical side face, of a depending member secured to said face and having its car or engine are to lower end reduced and threaded, a horizonthe opening of the clamp and having a nut 10 tal member adapted to be disposed transengaged thereon. i A. Y versely beneath the rail between the ties, one 1n testimony whereof Iax my `Signature end of the horizontal member being iorneil in the presence of two witnesses:

with an aperture receiving the said threa e end, a clamp arranged for engagement with HOLDMAN i the base flange of the rail and having an Witnesses:

opening therethrough, the outer end of the Y L. F. CARR,

horizontal member being disposed through EDNA MOYER.
